Entrée is a mayo loving tasty mutant who is Peri's friend and one of the main characters on the show. Entrée is more stupid than Peri. Sometimes when Peri doesn't play with him for a long time, he turns evil and takes revenge on him.

It was believed that the Doctor created him for the purpose of being eaten, hence his name.

Due to his short attention span, he mostly fails to consider the consequences of his actions, even regarding others, even to himself or parts of himself (his stomach), using Poosh to tire himself out without knowing. It even resulted in Entrée's stomach, heart and brain going on strike due to the abuse meted out against them.
